Hi, I could not reproduce the issue with an up-to-date Xubuntu 20.04 LTS which is featuring Thunar 1.8.14-0ubuntu1.
So I took a quick look at the commit history of the project. I found a potentiel commit candidate that provides a fix for the issue reported: https://gitlab.xfce.org/xfce/thunar/-/commit/adca28cea8eeb8efd457cd794271eee72867c23d | commit adca28cea8eeb8efd457cd794271eee72867c23d | Author: Reuben Green <reubengree...@gmail.com> | Date: Fri Sep 20 11:04:00 2019 +0100 | | Ensure user customizable action uses currently selected file path (Bug #15119) | | Moves the call to thunar_standard_view_merge_custom_actions from thunar_standard_view_context_menu | to thunar_standard_view_selection_changed to ensure that the available menu items get updated | whenever the file selection changes, not just when a context menu is run.
